IMPROVEMENT IN HARROWFS.

Specification forming part of Letters Patent No. 12,659, dated April 3, 1855..

Toy all whom -it may concern.-

Be it knownthat I, GHARLEs GLARENI, of the city, county, and State of New York, have invented a new and useful Improvement in Harrows, which Ivdenominate the Horizontal Flexible Self-RotatingHarrow 5 and Idohereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of the same, in which- Figure 1 is a plan of theimplement. Fig. 2 is a vertical section. Fig. 3 is a plan of the center castings' underside. Fig. 4 is a modiication of the rotating apparatus.

The construct-ion ot' my improved harrow is `as follows: I form a pole, a, of sufficient length, to which the horses or other animals are hitched to draw the implement. Tothe rear end of this pole, a pivot, b, is affixed, on which, below the pole, a circular metal plate, e, rotates. This plate`(shown detached at Fig'. 3) forms the center ot' the harrow. It has three (more or less) radial dan ges projecting from its under side, the outer end ofeach of which is divided at c', as clearly shown in Fig. 3, so as to form a bearing for the movable section of the barrow to pivotin a casting, d, having two radial projections, d d', upon it,jointed toithe center piece. The projections d! have wooden arms e firmly bolted to them, to the `outer ends of which a wooden segment, f, is aixed, which, together with the arms, is sufficiently stout to support the barrow-teeth '13, that are inserted in them. The barrow is divided into sections, (three being represented inthe draw- .ings,) each being allowed to rise and fall independent ofthe others to suit themselves to the inequality of the surface over which'they are drawn. v

To cause the implement thus constructed to revolve as it is drawn forward in a straight line, one modification is to athx to the rear end of the pole and across the center of the harrow a bar, g, extending from 'side to side thereof, and at right angles to the pole this barsupports an axle, 7c, in proper bearing, projecting from its under side. 0n the ends of the axle lc, beyond the periphery of the harrow,two sets of spade-like arms, l, are affixed, radiating from a hub upon the axle-like spokes of a wheel. These are turned by coming in contact with the ground, and cause the barrow Ato rotate horizontally by means of a pinion, m, on the axle, which gears into a bevel-wheel, n, attached to or forming a part. of the center casting of the barrow c.

Another device, which I deem more simple and important,is to dispense with the cross-bal g and axle lf, together with the gear-wheel and pinion, and instead thereof to joint to the curved segments j' certain movable spades s, as shown in Fig. 4., which will fold up toward the segments, as shown by the dotted lines, in one direction, but can only be brought down nearly to a perpendicular line, in the othe'r by reason of a shoulder or cross-piece that strikes l. Making the rotating barrow in flexible segments, as herein described.

2. The movable spades s for rotating the barrow, as herein specified.
